- Color temperature
- 6500 K
- AR coated glass
- mechanical rear, forward clicky
The throw is the calculated distance in meters at which the flashlight produces a light intensity of 0.25 lux. The candela per lumen (cd/lm) ratio can be used to determine if a flashlight has a spot or flood type beam. Well-focused spot beams can be over 100 cd/lm, tactical flashlights are typically between 20-100 cd/lm, and work lights are less than 10 cd/lm.
- 2300 lm
- 129600 cd
- 720 m
- CD/LM factor
The L21A SST40 CW has mode memory. Mode memory means that the light will remember the mode you were using when the light was last turned off, and when you turn it on again.
- 4 modes
- Mode memory
- Ramping mode
The L21A SST40 CW cannot charge batteries directly. You may need an external charger to keep your battery going. This flashlight has a built-in low voltage protection (LVP) to prevent damage to the cell from over-discharge, so protected cells are not necessary. The built-in thermal control automatically adjusts brightness output to prevent overheating.
- 1 x 21700 Li-Ion battery
- Battery indicator
- Charger port
- Thermal regulation
- AUX LEDs
The performance of the Convoy L21A SST40 CW flashlight is measured according to the ANSI / NEMA FL1 Standard 30 seconds after switching the light on. The ANSI/NEMA FL1 2009 Standard is a set of flashlight performance guidelines.
The specifications above are based on the official data published by the manufacturer, but we also take user reviews into consideration. If you found an error or something lacking in the specifications above for the Convoy L21A SST40 CW, then don’t hesite and signal the problem to us.
